US3 Serine/Threonine Protein Kinase from MDV-1, MDV-2, and HVT Differentially Regulate Viral Gene Expression and Replication.

ABSTRACT: Gallid alphaherpesvirus 2 (GaHV-2), commonly known as Marek's disease virus type 1 (MDV-1), is an oncogenic avian alphaherpesvirus, and along with its close relatives-Gallid alphaherpesvirus 3 (GaHV-3) or MDV-2 and Meleagrid alphaherpesvirus 1 (MeHV-1) or turkey herpesvirus (HVT)-belongs to the Mardivirus genus. We and others previously showed that MDV-1 US3 protein kinase plays an important role in viral replication and pathogenesis, which could be partially compensated by MDV-2 and HVT US3. In this study, we further studied the differential roles of MDV-1, MDV-2 and HVT US3 in regulating viral gene expression and replication. Our results showed that MDV-2 and HVT US3 could differentially compensate MDV-1 US3 regulation of viral gene expression in vitro. MDV-2 and HVT US3 could also parti
